How to Convert Watts to Kilocalories per Hour
The watt and kilocalorie per hour are both units of power. 1 kilocalorie per hour equals 1.163 watts. This means to convert watts to kilocalories per hour, you divide by 1.163.
Formula
Step-by-Step Example
Convert 5 W to kilocalories per hour:
We need to convert watts to kilocalories per hour
Since 1 kcal/h = 1.163 W, divide by 1.163
5 ÷ 1.163 = 4.2992261393
5 W = 4.2992261393 kcal/h

About These Units
Watt (W)
The watt (W) is the SI unit of power equal to one joule per second. Watts measure electrical power consumption (LED bulb: 10W, microwave: 1000W), light bulb brightness, and device power ratings. One kilowatt equals 1,000 watts. Named after inventor James Watt.
Kilocalorie per Hour (kcal/h)
Kilocalories per hour (kcal/h) measures metabolic rate and heat production, equal to 1.163 watts. Basal metabolic rate is about 60-80 kcal/h. Exercise increases metabolic rate to 300-900 kcal/h depending on intensity. Also called "large calories per hour."
